This book is a compilation of personal histories, official accounts, and non-official published accounts of the PATHFINDER into a volume by NOAA to share with officers, scientists, technicians, and vessel operators of the Naval Meteorology and Oceanography Command (NMOC). This resulting compendium of PATHFINDER lore is primarily directed towards the WWII exploits of the USS PATHFINDER, but it also traces the career of the vessel through to its final decommissioning.
